3. Add bran mixture to yeast mixture, along with remaining 2 1/2 cups flour, flax meal, and salt. Using a bread hook, mix on low speed 7 minutes. Form dough into a ball, place in a greased bowl, cover with plastic wrap, and allow to sit in a warm place until doubled in bulk, about 1 1/2 hours.

4. Punch dough down and remove from bowl. Knead lightly and shape dough into a loaf. Place in a greased 9-inch loaf pan, cover lightly with a clean dish towel, and let rise until bread rises about 1 inch above pan rim, about 30 minutes.

5. Position a rack in the middle of the oven and preheat oven to 350 F. Bake bread until dark brown, about 30-35 minutes. Remove from pan immediately and allow to cool at least 30 minutes before slicing.
